| 摘 要： | In our work,ocean ridge granite,i.e., Oytan plagiogranite massif,was discovered in western Qinghai-Xizang plateau.It intruded into the basic lava of the Oytag ophiolite suite and it was formed a little later than the (ultra)mafic rocks of the Oytag ophiolite suite.The Oytang plagiogranite possesses the geochemical characteristics of mantle-source granite and was formed in the “supre-subduction zone”(SSZ)ocean ridge environment,like the ocean ridge granite of Troodos,Cypus. |

| Abstract: | In our work, ocean ridge granite, i.e., Oytag plagiogranite massif, was discovered in western Qinghai-Xizang plateau. It intruded into the basic lava of the Oytag ophiolite suite and it was formed a little later than the (ultra) mafic rocks of the Oytag ophiolite suite. The Oytag plagiogranite possesses the geochemical characteristics of mantle-source granite and was formed in the “supra-subduction zone” (SSZ) ocean ridge environment, like the ocean ridge granite of Troodos, Cypus. |
